| Project Description |
New build IGCC plant capturing 65% of CO2 emissions. In collaboration with Shenhua since 2014 for development of technology. CO2 will be sold to Denbury for EOR supply.
Construction planned 2012 to 2014, but overran and commissioning spanned to 2017. Generation plant running on natural gas since July 2014.
Gasifiers commissioned Dec 2014 to Nov 2016 but further maintenance required on gas cleaning system, ash removal system and tube leaks in syngas cooler.
Periods of integrated operation on both gasifiers achieved in Jan, Feb 2017, including supply of CO2 to pipeline.
Project delays resulted in Mississippi Power having to repay USD 234 M in tax credits and losing a 15% ownership deal with power purchasing cooperative SMEPA.
The State allowed an increase in electricity prices to support the project and US DoE allocated further support (USD 100 M) from unspent "clean coal" funds specifically to protect further changes to consumer prices.
July 2017, the state regulator issued an order preventing Mississippi Power from passing on any further costs to customers, and requiring removal of risks associated with lignite gasification - essentially cancelling IGGC and CCS aspects of the project and limiting it to burning natural gas.
In a separate project (status now uncertain), funded to USD 11 M by USDoE under the CarbonSAFE programme, the Southern States Energy Board will characterise a potential commercial storage site adjacent to the Kemper project. (Updated 20/07/17) |
